We divide 83359543 by 601
The aim is to understand the frequency of 601 in 83359543.

Step 1:
When dividing 8 by 601, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (3) from the dividend after 8, then repeat: 83 / 601

Going ahead to step 2:
601 can be fit into 83 0 times, resulting in a remainder of 83.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 83 and we're left with 83.
Include the next digit (3) from the dividend after 83, then repeat: 833 / 601

Advancing to step 3:
601 goes into 833 1 times with a remainder of 232.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 601 from 833 leaves us with 232.
Include the next digit (5) from the dividend after 232, then repeat: 2325 / 601

Advancing to step 4:
601 can be fit into 2325 3 times, resulting in a remainder of 522.
Write down 3 as next digit of the result. 
Result so far: 13.0
Subtract 1803 from 2325 to get 522.
Bring next digit (9) of the dividend behind the 522 and repeat the process: 5229 / 601

Going ahead to step 5:
5229 divided by 601 is 8 with a remainder of 421.
Use 8 as the next digit of our solution. 
Result so far: 138.0
Subtracting 4808 from 5229 leaves us with 421.
Include the next digit (5) from the dividend after 421, then repeat: 4215 / 601

Step 6:
The number 601 fits into 4215 7 times, leaving a remainder of 8.
The number 7 becomes the next digit in our result. 
Result so far: 1387.0
The remainder is 8 after subtracting 4207 from 4215.
Grab the next digit (4) from the dividend, add it to 8, then carry on: 84 / 601

Going ahead to step 7:
601 can be fit into 84 0 times, resulting in a remainder of 84.
The next digit of our result is 0. 
Result so far: 13870.0
If we take 0 away from 84, we end up with 84.
Include the next digit (3) from the dividend after 84, then repeat: 843 / 601

Going ahead to step 8:
When dividing 843 by 601, we get 1 with a remainder of 242.
Use 1 as the next digit of our solution. 
Result so far: 138701.0
If we take 601 away from 843, we end up with 242.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

On to step 9:
The number 601 fits into 2420 4 times, leaving a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 138701.4
Deduct 2404 from 2420 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 10:
When dividing 160 by 601, we get 0 with a remainder of 160.
Record the quotient 0 as the next digit in the result. 
Result so far: 138701.4
Deduct 0 from 160 and we're left with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Moving on to step 11:
If we divide 1600 by 601, we get 2 and a remainder of 398.
Write down 2 as next digit of the result. 
Result so far: 138701.402
The remainder is 398 after subtracting 1202 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3980, and continue the process.

Step 12:
When dividing 3980 by 601, we get 6 with a remainder of 374.
The next digit of our result is 6. 
Result so far: 138701.4026
Deduct 3606 from 3980 and we're left with 374.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3740, and continue the process.

Advancing to step 13:
If we divide 3740 by 601, we get 6 and a remainder of 134.
Use 6 as the next digit of our solution. 
Result so far: 138701.40266
The remainder is 134 after subtracting 3606 from 3740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Our division results in 138701.40266 with a remaining 0.000134.
